Newt Gingrich – who last campaigned in Iowa for his 2012 presidential bid on May 21 – will return to Iowa during the July 4 holiday.

Additionally, Will Rogers, the director of the former U.S. House speaker’s Iowa grass-roots campaign, has resigned.

Craig Schoenfeld, executive director of the Iowa campaign, is resisting national media reports that the campaign is troubled and said this morning that the developments did not signify distress.

Rogers, a former co-chairman of the Polk County Republican Party, will continue to work as a volunteer for the Gingrich campaign. He’s returning to his job as the director of government affairs for the Iowa Nebraska Equipment Dealers Association, Schoenfeld said.

Schoenfeld said that “campaigns in and of themselves are unstable,” with comings and goings routine.

Gingrich’s rough start stems largely from a May 15 “Meet the Press” interview, when he called the House Republicans’ Medicare plan “too big a jump.” In the same interview, he criticized “right-wing social engineering” and “imposing radical change.”

Rogers could not immediately be reached Saturday for comment. Schoenfeld said details of Gingrich’s planned trip to Iowa over the July 4 holiday will be released later.
